Bitcoin News Today: IREN Shares Jump 11.4% After Outproducing MARA in July Bitcoin Mining

Shares in IREN Ltd surged 11.4% on Wednesday after the Bitcoin miner reported mining 728 BTC in July, outpacing MARA Holdings, which mined 703 BTC during the same period [1]. This marked a significant operational win for IREN, which managed the feat despite deploying a smaller hashrate—50 exahashes per second (EH/s) compared to MARA’s 58.9 EH/s—demonstrating the efficiency of its operations [1]. IREN also reported an average hashrate of 45.4 EH/s for the month, indicating that a majority of its mining rigs remained operational and productive [1].

The strong results coincided with a challenging environment for Bitcoin miners due to a recent rise in mining difficulty, which increases energy consumption and threatens profitability if not offset by more efficient hardware or reduced electricity costs [1]. Despite these headwinds, IREN’s July revenue hit $86 million, with $2.3 million coming from its expanding artificial intelligence cloud business [1]. The company has been diversifying beyond Bitcoin mining, including a purchase of 2,400 NVIDIA Blackwell GPUs in early July, with the first shipment of 256 units already received [1]. Co-founder and co-CEO Daniel Roberts emphasized the company’s ability to run both Bitcoin mining and AI operations on the same infrastructure, underscoring its adaptability [1].

IREN’s share price closed at $18.32, pushing its market cap to $4.11 billion, the second-highest among public Bitcoin miners, behind only MARA [1]. This performance came just over a year after short-seller Culper Research labeled IREN as “wildly overvalued,” questioning its ability to compete in AI with limited investment [1]. Since then, IREN shares have rebounded sharply, rising more than 227% from their low of $5.59 in April [1].

The broader Bitcoin mining sector remains volatile, with miner stocks reacting swiftly to operational and market developments. IREN’s ability to outproduce a larger competitor highlights the importance of operational efficiency in a sector where small improvements in hash rate and cost control can significantly influence profitability [1]. As the industry continues to consolidate and evolve, companies that demonstrate both technical and strategic agility are likely to attract investor attention [1].

IREN’s performance also aligns with a broader trend of firms treating Bitcoin as both a revenue stream and a balance sheet asset. This approach has been mirrored by other companies that have added substantial BTC holdings to their treasuries in recent months [1]. As the market digests these developments, the ability of miners to adapt to shifting conditions—whether through diversification into AI or through strategic Bitcoin accumulation—will be key to long-term success [1].
